Looked it up to see what it is, I can't find anything on a 1901.

I've never run one of these, but I'm sure it could be made to work. It looks like the secondaries are kind of a quasi 3-4 barrel design. I cannot tell if the throttle blades will work with your stock intake. You may have to run a spacer under the carb with a stock intake. Are you planning to upgrade the intake at the same time? You have a T5 so you don't have to mess with the AOD TV connection which will simplify the install. Also no guarantees this will fit under your stock air cleaner. Carb swaps are usually a lot of fun because the fit affects so many other different parts and you never know how everything will fit together until you have it sitting on top of the intake.

That's (1901) a Carter/Edelbrock clone, a 625 "Street Demon". The secondary/rear throttle plate is a "B" shape and opens forward-down, so shouldn't be an issue bolted onto any 4-barrel intake manifold that will accept a Carter/Edelbrock carburetor.
If you haven't yet, it's a good idea to look at these:

Their can be no happiness with out Goggle Valve Secondaries.....
Its a Carter Themoquad polycarbonate base carb with a Holley 3 barrel secondary trap and Quadrajet Triple boosters in a Demon wrapper....made by Holley!
If the jets and metering rods are right, then all you need to make it run is the right fuel pressure, manifold port and leak free base to mount it on. And make sure you got the right air cleaner hookups.

I ran one of those street demon carbs before I put the blower on my car. I really liked it- it had the no gaskets below the fuel level and the easy metering rod changes of an Edelbrock, with the easily adjustable secondary opening time of a Holley, and better transition between the idle/part throttle and full throttle than the Edelbrock ever had. I never dove into tuning it too deeply since I went to a mechanical secondary Holley with the blower, but i wouldn't hesitate to recommended one. That being said, whatever you go with, plan on tuning it- either yourself, or pay somebody who knows how. If you are going to pay to have it done, finding someone to tune a standard Holley is probably going to be far easier than any other option.
